Description

The invention relates to an improved hanging bracket for mounting wall cabinets, such as, for example, wall blocks and blocks based on a base, for kitchens and bathrooms, or other furniture that must be fixed cantilever to a supporting wall.

Known metal suspension brackets containing a shaped base having a substantially rectangular shape.

On this basis, a bracket with a hook-shaped end is installed, extending from the base and configured to adjust the position.

The base is attached to the wall of the wall cabinet by fixing means, such as screws, and / or pressure or expansion pins, or other fixing means, while the hook is attached to a support attached to the wall - an expansion bolt shield, a plate, a shaped strip or similar product.

Two adjustment mechanisms interact with the bracket itself for regulating, respectively, its height (vertical) and depth.

The wall cabinet can be mounted on the wall in the required position, as well as with respect to adjacent cabinets.

A pendant arm of this type is described and illustrated, for example, in patent documents PCT / EP 2009/005627 and PCT / EP 2009/005628, which are referred to for explanation and which should be considered as an integral part of this invention.

The suspension brackets of this type, briefly described above, are attached to the wall of the piece of furniture either manually or using an automated assembly line equipped with a vibrating feeder to feed the suspension bracket in a proper position to the automatic fastening device of the specified line to the wall of the wall cabinet.

As is well known to those skilled in the art, due to vibration of the vibrating feed means, the adjustment screws may be tightened or loosened (depending on the direction of rotation of the vibrating feed means clockwise or counterclockwise) of the height and depth of these mechanisms that the suspension bracket is equipped with.

This circumstance is a significant drawback, since the indicated adjustment screws of the suspension bracket move and occupy a position different from the position set by the manufacturer of the suspension bracket for its correct use, both for manual and automatic fixing of the bracket to the cabinet wall, as well as for simple, correct and quickly attaching the cabinet to a support attached to the wall.

The aim of this invention is to eliminate the aforementioned drawback of the prior art by creating a suspension bracket with adjusting mechanisms in height and depth, equipped with adjusting screws, the position of which cannot in any way be accidentally changed due to vibrations of a vibrating feed means or similar tool.

This goal is achieved by means of a suspension bracket having the characteristics specified in paragraph 1 and in the dependent claims.

The structural and functional characteristics of the invention and its advantages over the prior art will become apparent from the following description with reference to the accompanying drawings, illustrating examples of embodiments of the invention.

In the drawings:

FIG. 1 is an enlarged view along arrow A shown in FIG. four;

FIG. 2 is an enlarged view along arrow B shown in FIG. four;

FIG. 3 is an enlarged view along arrow C shown in FIG. one;

FIG. 4 is an enlarged view along arrow D shown in FIG. one;

FIG. 5 is a plan view along arrow E shown in FIG. one;

FIG. 6 and 7 are perspective views illustrating the suspension bracket shown in FIG. 1-5;

FIG. 8 is a sectional view taken along line VIII-VIII of FIG. one;

FIG. 9, 10, and 11 are enlarged sectional views illustrating processing steps of the proposed suspension bracket; and

FIG. 12 and 13 are perspective views similar to those shown in FIG. 6 and 7, illustrating the same hanging bracket provided with various means for attaching it to the shoulder of a piece of furniture.

As shown in FIG. 1-8, the proposed metal suspension bracket, designated generally by the position number 20, structurally consists of a shaped base or frame 21, which has a substantially rectangular shape and on which the bracket 22 is mounted in an adjustable position (with the possibility of rotation and movement).

As can be clearly seen in the drawings, the bracket 22 has two opposite sides or sides 23, covering the base 21 and extending from it in the form of a hook-shaped end 24.

Two adjusting mechanisms interact with the bracket 22, namely, the first mechanism 25, designed to adjust the height, and the second mechanism 26, designed to adjust the depth.

The suspension bracket made in this way is attached to the cabinet wall, for example, using self-tapping screws (not shown) passing through the holes 27 of the base 21.

The hook 24, on the other hand, can be engaged by engagement with a support attached to a wall, for example, a wall plug, plate, plank or similar.

More specifically, the first height-adjusting mechanism 25 includes an arcuate part 28 that slides along the base 21. The lower end of the part 28 acts on the bracket 22, while its upper end cooperates with the adjusting screw 29 screwed into the nut 30 secured to the base 21.

The screw 29 has a head 31 with a stamping under the working tool. Arcuate supports 32 of the base 21 support the shaft of the screw 29.

The second depth adjusting mechanism 26 comprises an adjusting screw 33 acting on the end of the bracket 22 opposite the hook 24.

The screw 33 is screwed into a nut 34 mounted on the bracket 22. The bracket 22 and the arcuate support 35 of the base 21 support the shaft of the screw 33, and the support 35 together with the end teeth 39 of the base 21 itself define the receiving socket 40 for the head 41 of the screw 33 with a stamping 42.

From the above description with reference to FIG. 1-7, and also as is well known to specialists in this field of technology, it follows that after mounting the cabinet on the wall, turning the height adjusting screw 29 will cause oscillation around the portion 43 of the bracket 22 in the direction of arrow F, while turning the adjustment screw 33 depth, will cause the movement of the same shoulder 22 in the direction of the arrow F1.

The operation of the height and depth mechanisms of the pendant bracket under consideration is also illustrated in detail in the aforementioned patent documents PCT / EP 2009/005627 and PCT / EP 2009/005628.

In accordance with this invention, an undesired accidental rotation (tightening or loosening) of screws 29 and 33 is prevented by, for example, created by the above vibrating feeding means, by fully pulling the bracket 22 to the base (21) by tightening the screw 33, and this action forces the bracket 22 occupy the horizontal position shown in FIG. 1 and 2. When the bracket 22 is located in a precisely horizontal position, the screw 29 cannot be screwed on (since it abuts against the arcuate element 28 and, accordingly, the bracket 22, which is fixed in horizontal position by tightening the screw 33) and cannot be unscrewed ( since due to deformation d in its threaded part, which is connected to the nut 30, it creates friction during rotation, which prevents this rotation).

The indicated deformation d in the threaded portion of the screw 29 can be clearly seen in an enlarged view in FIG. eleven.

As can be clearly seen in FIG. 9 and 10, deformation d is obtained using a punch 36 and a counter punch 37, between which a suspension bracket 20 is arranged.

FIG. 12, 13 show a suspension bracket completely similar to the suspension bracket shown in FIG. 1-11, except that, as fasteners used for fastening to the cabinet wall, instead of holes 27 for screws, push pins 38 (so-called dowels) are actually provided.

Thus, the goal set at the beginning of the description is achieved.

The scope of legal protection of the invention is defined in the following claims.
